I bought two $5 ConeTopia deals from Livingsocials a while ago and I used them both yesterday for lunch.
The owner was very nice. I showed him the two vouchers and he accepted them both without questions, he explained to us where ConeTopia came from and recommended Cone Pizza flavours. We got 2x Pizza cones, 2x small chips, 2x drinks (soft drinks/juice) and 2x gelato in a cup. The pizza cones are usually $5.90 by themselves so this was definitely a good deal. They didnt give us looks and served us regular size foods - which is pretty unique considering from what I read on other group buy threads.
Since the lunch was free (using the LivinSocial free credit) and the owner was so nice, the least I could do was to review my experience. I recommend them.
Definately a plus for conetopia :)
